I've read this before, but it never gets old. I love it when big-time comics people lampoon their image this way. (And given the sheer amount of characters that the two of them created, a hero whose liver lights up in the presence of danger is not all that farfetched - if they'd kept going in the way they did for a few years longer, I'm guessing they'd end up resorting to ideas like that on a semi-regular basis.)
